Which one of the following is used as internal standard in NMR analysis?

Pulegone on reaction with $KMnO_{4}$ forms:

Assertion (A): Enantiomers are inseparable on simple column chromatography. Reason (R): Enantiomers bind achiral stationary phase with equal affinity and Enantiomers can be separated by using chiral stationary phase.

Assertion (A): HBr addition to alkenes gives Markonikov addition. Reason (R): HBr addition to alkene in the presence of peroxide gives Anti-Markonikov addition as the reaction proceeds via radical mechanism.

Assertion (A): Carbon halogen bond in aryl and vinyl halides are unusually shorter. Reason (R): Chlorobenzene and vinyl chlorides undergo $S_N1$ and $S_N2$ reaction in general.

Assertion (A): In $S_N1$ reaction racemic mixture is formed and in $S_N2$ reaction inversion of configuration is observed. Reason (R): $S_N1$ reaction is concerted mechanism and $S_N2$ reaction involves carbocation intermediate.
